Related to concentric exercise: isokinetic exercise, eccentric exercise


To implement the right of the holder of an option to buy (in the case of a call) or sell (in the case of a put) the underlying security.


In option contracts, to buy (in the case of a call) or sell (in the case of a put) the underlying asset. The option holder has no obligation to exercise the option, and only does so if he/she believes it benefits him/her. Depending upon the nature of the option, this may be done at any point during the life of the contract, or it may only be done on the contract's expiry date. The strike price of the sale is agreed-upon in the option contract, that is, before the option is exercised.


To require the delivery (for example, a call option) or to force the purchase (for example, a put option) of the option's underlying asset. Many options expire without being exercised because the strike price stated in the option is unfavorable to the holder.


When you act on a buying or selling opportunity that you have been granted under the terms of a contract, you are said to exercise a right.

Contracts may include the right to exchange stock options for stock, buy stock at a specific price, or buy or sell the security or product underlying an option at a specific exercise price.

For example, if you buy a call option giving you the right to buy stock at $50 a share, and the market price jumps to $60 a share, you'd likely exercise your option to buy at the lower price.

With regard to kidney tissue, the considerable responsiveness to concentric exercise (Figure 1) was indeed expected, if one considers there was an increase in blood pressure and glomerular pressure, resulting in turn, from a variety of factors such as dehydration, hyperfiltration of damaged enzymes and other proteins originated in the micro-lesions (Bassit et al.
The animals undergoing concentric exercise were also those that showed the greatest increases in creatine kinase and lactate dehydrogenase activities, consistent with the highest concentrations of HSP70 observed in most of the tissues analysed.
In addition, it was interesting to observe that the metabolic stress, more associated with concentric exercise than with downhill exercise, seemed to elicit a greater response from the mechanism that produces the HSPs than the physical stress known to produce tissue injury, which typically occurs in the eccentric exercise.
Concentric exercises involved lifting the body weight with the injured leg, lowering with the uninjured leg, and progressing to include other standard concentric strength exercises.
